Abstract: 1,225,404. Metal treatment Deoxidation. KAISER INDUSTRIES CORP. July 22, 1968 [Aug.3, 1967], No.34948/68. Heading C7D. Ferrous metal substantially free from oxygencontaining impurities is prepared by lowering the dissolved oxygen content in a preliminary deoxidation to not more than that given by the formula Log 10  %0 = 7640/T(‹ K)+2À84 and, if aluminium is used for this deoxidation, not more than that which is related to the aluminium present by the formula Log 10  [(%Al)<SP>2</SP>. (%O)<SP>4</SP>] = -79600/T (‹ K)+32À15, separating the preliminarily deoxidized metal from deoxidisation products and subjecting it to further treatment. The further treatment involves preparing a chamber lined with refractory containing 3À5% Feo or less which will not yield oxygen to molten metal containing aluminium as a deoxidizer, passing a non-oxygen-yielding gas into the chamber, adding a stoichiometric excess of aluminium over that theoretically required to deoxidized the metal, introducing the metal into the chamber, maintaining the chamber above the melting point of the metal until deoxidation has reduced dissolved oxygen in the metal to not more than 0À006% by weight and separating insoluble material from the deoxidized molten metal. Other agents such as hydrogen or carbon may be used for the preliminary deoxidation.

Abstract: 1,227,740. Measuring speed electrically. ASTON MARTIN LAGONDA Ltd. Sept.25, 1968 [Sept. 27, 1967], No.43883/67. Heading G1H. [Also in Division F2] An anti-skidding pneumatic braking system comprises means to interrupt a fluid-flow from a pedal-operated master cylinder 10 to slave cylinders 23 when the deceleration of a wheel (or wheels) rises above a predetermined value. Electronic counters 24, one adjacent the periphery (25) of each brake disc 26, supply pulse trains, of which the repetition frequencies depend on the wheel velocities, to a comparator 29 via respective rectifiers 27 and amplifiers 28. The output voltage of the comparator is fed to a solenoidoperated valve 13 in which energization of a solenoid 21 draws a plunger 19, against a spring 20, so that spring 17 urges a ball 16 to seal an orifice 15 in the fluid-flow path between a first chamber 12, of the valve, connected via conduit 11 to the master cylinder and a second chamber 14 connecting via conduits 22 to the slave cylinders. The effective volume of this latter chamber is increased by the introduction of a reduced-diameter section 18 of the plunger into the chamber, thus the fluid-pressure at the slave cylinders is decreased and the brakes are released. When the deceleration falls below the predetermined level the solenoid is de-energized and braking pressure is re-applied. In a second embodiment Fig.2 (not shown) pulses from the two front wheel counters 24 are combined and led via rectifier (30) and amplifier (31) to a first input of a comparator 29, to which a second input is applied being similarly derived from the two rear wheel counters, so that when the difference exceeds a predetermined level the output voltage is applied to one of two solenoid operated valves (34, 35) which control the fluid-flow to the slave cylinders on the front and rear wheels respectively. Fig. 4 (not shown) illustrates the notches on the periphery (25) of the disc, which produce pulses by interaction with the magnetic field of a counter. An alternative embodiment Fig. 5 (not shown) illustrates a plurality of equi-spaced axial holes (36) drilled in a concentric row near the disc periphery, the counter 24 being mounted parallel to the axis of the disc and at the same radius as the row of holes so that the rotating holes interact with the magnetic field of the counter to generate pulses. In a third embodiment Fig. 6 (not shown) the holes are radially disposed at the periphery and the counter 13 mounted radially. The discs may be replaced by similarly notched drums.

Abstract: 1,264,135. Decorative coating. FOSTER PLASTICS (RAINFORD) Ltd. 7 March, 1969 [5 Oct., 1968], No. 47328/68. Heading B2E. A decorative finish on a smooth non- porous substrate surface is produced by applying a coating of a coloured hardener for an unsaturated polyester resin, allowing the coating to dry, applying in a pattern a solution of silicone gum dispersed in a solvent or in a polyester lacquer, allowing the surface to dry and thereafter applying an over-all coating of an unsaturated polyester resin lacquer and allowing the lacquer coated surface to dry in a dust-free atmosphere. The polyester resin component of the lacquer is an unsaturated polyester formed from polyhydric alcohols and unsaturated di-basic acids or anhydrides dissolved in a polymerisable vinyl monomer, e.g. styrene. The unsaturated polyester resin lacquer may contain metal powder. Antique beaten metal effects or ceramic tile effects can be produced. A further clear coating of polyester lacquer or of polyurethane resin may be applied.

In an air conditioner including a reversible compression refrigerating system having indoor and outdoor heat exchangers 3 and 5, the indoor heat exchanger 3 comprises first and second heat exchangers 3<SP>1</SP> and 3<SP>11</SP> between which refrigerant heating means 6 is inserted. During the heating cycle (solid arrow lines) wherein room air to be heated passes through the indoor heat exchanger 3, refrigerant gas from the compressor 1 passes into the first heat exchanger 3<SP>1</SP> where it is partially or wholly condensed and then through conduit 10 into the heating means 6 where it accumulates and is heated by an electric heater 7 and partially evaporated. The gas-liquid mixture leaving the heating means 6 through an upper conduit 11 enters the second heat exchanger 3<SP>11</SP> where the gaseous refrigerant is condensed again. Refrigerant is returned to the compressor 1 by way of capillary tube 4, outside heat exchanger 5, four-way valve 2 and accumulator 14. The electric heater 7 together with an overheat thermostat 9 is mounted within -an externally finned tube 8. In a modification (see Fig. 8, not shown) the refrigerant is heated directly by the electric heater. An electric circuit (see Fig. 3) is provided for controlling the compressor 1 and heater 7, the heater being actuated during the heating cycle only when the compressor is in operation. The speed of a fan discharging air into the room is controlled in dependence of the temperature of the discharging air. For removing frost formed on the surface of the outside heat exchanger when the outside temperature is low, the air conditioner is switched to the cooling cycle and the electric heater is energized to raise the refrigerant temperature and thereby speed up the defrosting: the fan is stopped during defrosting.

In a first embodiment, as shown, a collar 42 retains the flexure assemblies 16, 18 which further abut a flange 54 on the inner housing 14. The housings 12, 14 may be welded directly to conduits (not shown). The flexure assemblies 16, 18 are made as integral units prior to placement in the joint. The element 20, segments of reinforcement 30, 32 and a rigid sleeve 52 which may be of steel for example, are placed in a mould into which a resilient material such as a polyurethane casting compound is poured and cured to produce layers 28. Other reinforcing materials may be used e.g. reinforced plastics, titanium, aluminium and other metals, or materials such as chopped glass fibres, glass fibre cloth, silica fibres and metal fibres may be randomly dispersed in the resilient material. Other suitable resilient materials are natural or synthetic rubber or other elastomer e.g. polysulphide, nitrile, neoprene, butyl, and ethyl propylene. Bores 68 allow fluid in the pipe to enter a cavity 70 to equalise pressures on the assemblies 16, 18. In another embodiment the outer spherical surfaces of flexure assemblies (76, 78) (Fig. 3 not shown) are bonded to outer housing and closure cap surfaces (102) (104) and the annular shear element (86) has an outer frusto-conical surface (92). In both embodiments, when an axial pull is applied to the joint one of the flexure assemblies 16, 18 is compressed axially and the other extends leaving a gap (A) (Fig. 5 not shown) between the flange 54 and rigid member 20. Stresses on the assemblies 16, 18 are relieved by the yieldable shear elements 50 to maintain the flexibility of the joint. A further embodiment (130) (Fig. 4 not shown) includes ball and socket members (132), (148) on the inner housing and coupled outer housings (156) (154) retain the flexure assemblies (150) (152).
